The more economically advanced countries in the Developing World have better overall safety records than the others, but even their death risk per flight is seven times as high as that in First World countries.
These statistics are among the findings in the new study Cross National Differences in Aviation Safety Records by Arnold Barnett, which appears in the current issue of Transportation Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS®). Barnett is a Professor of Operations Research at MIT’s Sloan School of Management and a long-term researcher on aviation safety.
Using worldwide air-safety data, Prof. Barnett calculated that, over 2000-07, the chance of dying on a scheduled flight in a First World nation like the U.S., Japan, or Ireland was 1 in 14 million (this statistic considers propeller planes as well as jets). At that rate, a passenger who took one flight every day would on average go 38,000 years before succumbing to a fatal accident. On the airlines of economically advancing countries in the Developing World such as Taiwan, India, and Brazil, the death risk per flight was 1 in 2 million. In less economically-advanced Developing-World countries, the death risk per flight was 1 in 800,000. Prof. Barnett calculates that the risk differences in this three-group model “are not statistically significant within groups, but are highly significant across groups.”
All these statistics reflect major advances in safety in the last decade, and Prof. Barnett points out that the distinction he makes is “between safe and very safe, and not between safe and dangerous.” Indeed, Prof. Barnett notes that “it is not uncommon for a month to pass without any fatal passenger-jet crashes anywhere in the world.”
While the study ends in 2007, the patterns it depicts continue to persist. So far in 2010, there have been eight fatal accidents on scheduled passenger flights. All eight of them occurred in the Developing World.
Prof. Barnett questioned why the economically-advancing countries in the Developing World did not have safety records closer to those in the First World, given that they approach First-World standards in life expectancy and per capita income. He cites research that indicates that, in terms of deference to authority and “individualism,” the economically advancing Developing-World countries are on average far from those in the First World but almost identical to other Developing-World countries. Prof. Barnett concedes that he should “not get too caught up in speculation,” but notes that one possible explanation for why the economically-advancing countries did not fare better is that “their economic shift towards the First World has not been accompanied by a corresponding cultural shift.”

INFORMS journals are strongly cited in numerous industry sources. BusinessWeek has added a fourth INFORMS journal to its list of journals used to determine the world's best business schools making INFORMS the scientific association with the largest number of scholarly journals on the prestigious list. The Financial Times includes four INFORMS journals in its list of academic journals used to evaluate and rank MBA programs. The ERA 2010 journal list available on the Australian Research Council (ARC) website gave 8 of the 12 INFORMS journals A rankings. The research influence and impact of INFORMS journals is measured by Thomson Reuters and is made available in their Journal Citation Reports. Several of our journals are ranked in the top 10 percent of their subject categories.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
